Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Hard Ginger Bread
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 300°F (150°C).
In a large bowl, mix molasses, sugar, and butter until well combined.
Add eggs and sour milk, mixing thoroughly.
Stir in baking soda and ground ginger.
Gradually add flour until the dough is manageable.
Shape and bake
Roll out the dough and cut into desired shapes.
Place on a baking sheet and bake for 35 to 40 minutes.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds sweetness, dark color and moisture, and gives the bread its characteristic flavor.
- Eggs
- Bind the dough and add structure as they set during baking.
- Sour milk
- Adds moisture and acidity that reacts with the baking soda to help the dough rise.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas, lightening the dough.
- Butter
- Adds fat for tenderness and richness in the dough.
The step that matters
Gradually add flour until the dough is manageable. Adding too much flour makes the dough dense and tough, because gluten develops with handling and extra flour dries the dough. Add it slowly so the dough stays soft enough to roll.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, butter, egg, milk, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against molasses, sugar, butter, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
